20 Claims. (01. 97-100) s PATENT v OFFICE 1 They present invention relates to gang plows, and more particularly to a bracing meansiorthe rear ends of the beams that carry the earth-working tools.

It is desirable in gang plows to maintain all of the earth-Working tools in a rigid position with respect to one another, so as to plow furrows of a uniform depth. It has been the practice to bolt a tie bar to the rear ends of the plow beams to hold the earth-working tools in a rigid position. This arrangement has been unsatisfactory since the pull of the earth-working tools on the tie bar would cause the bar to bend. It has also been found that the weight of the earth-working tools which will counteract stresses applied to the other side of the bar.

According to the present invention adjustable compression members are provided on the tie bar of the plow. These members can be adjusted s that the tie bar can be arched.

These and other objects and advantages of the present invention will be'apparent to those skilled in the art after a consideration of "the following detailed description of the invention, taken in conjunction with the accompanying drawings, in which:

nuts on the rods 28, 28a, 28b, 28c, and 28d, the

plow'frame l0 which consists of a plurality of longitudinally arranged plow beams l I connected .together at their front ends bya transverse bar 12. Theconventional wheel supports l3, I4, and

i5 and power lift 16 are shown in dotted lines. l'lare provided between the Brace members v At therearend of the beams H is bolted a curved beam ,lla whichhas an earthworking tool or plow bottom I8 secured thereto.

On each of the curved beams Ila is secured a bracket member IS with which is associated a The brackets H are provided with openings 2i. g 1,

A series of parts, 22 having openings 23 provided therein are associatedwith the brackets 19. Bolts 24 are inserted in the openings 2| in the brackets I9 and the openings 23 in the parts 22. Nuts25 are provided on each of the bolts 24 which, when tightened, secure the tie bar 20 to the brackets l9, j

Each of the parts 22' has a projection 28 in which there is provided an opening 21. The openings 21 are parallel to, and spaced from the tie bar 20. Rods 28 having threaded end portions-29 are inserted in the openings 21. Nuts 30 are provided on the threaded ends 29 of the rods 28.; As shown in Figures 1 and l, the tie bar 20 is held against fore and aft movement with respect to the brackets l9 by bolts 3| which are provided at opposite ends of the tie bar 20.

Referring to Figure 2, the plowbottoms are shown on the ground line 9:. In order that the nuts 30 on the rods 28 may be adjusted a block a is provided under. the centerplow bottom. The ground line is now at y. The weight of the plow bottoms on each side of the center plowbottom pulls the ends of the bar downwardly. The nuts 3|] on the rod 28 above the center plow bottom are then tightened against the sides of the parts 22.

The nuts 30 are tightened on the rods 28a, then 40 the nuts 30 on the rods 281), then the nuts on the rods 28c, and thenthe nuts 3|! on the rods 28d. The rods 28d are tightened against the parts 22 tie bar is held in its arched position. When the rods are all in compression, the block a is then removed, and 'the plow is supported on the wheels l3, l4, and I5. When the plow is in a transport position the weight of the plow bottoms on the tie bar 20 will pull thebar down into an approximately straight line position. 3 When the plow, is in an operating position the pull on the plow bottoms ,pulls the tie barinto anapproximately straight line position.- Should the tie bar at any time sag, Y

By tightening the an earth-working tool or plow bottom l8 secured thereto.

On each of the curved beams I la is secured an L-shaped bracket l9a having a series of holes provided therein. A tie bar 32, is associated with the top side of each of the L-shaped brackets, as shown in Figure 8. A series of plate members 33 and 33a. having openings provided therein. are

placed on top of the bar 32'. Bolts 34 are inserted in the openings in the bracket I901. and the openings in the plate members 33 and 33a. Nuts 34a are provided on each of the bolts 34 which, when tightened, secure the bar 32 to the brackets l9a.

The bracing means in this case comprises a pair of rods 35, the ends of which are welded to the platemembers 33a. A vertical plate 36, having socket members 31 welded thereto, is welded to the plate members 33. The ends of the rods 35 have threaded end portions on which nuts 38 are provided. The threaded ends of the rods 35 are inserted in the socket members 31.

The adjustment of the bracing means in this case is accomplished by also placing a block a under the center plow bottom. The weight of the plow bottoms will sag the ends of the beam downwardly so that the nuts 38 may be tightened against the sockets 31.

Another form of bracing means is shown in Figure 7. In this case the ends of a bar 35a are welded to the plate members 33a. The center of the bar 35a is welded to a vertical plate 3611 which is in turn Welded to the plate members 33. A bar 39 is also Welded to the plate members 33. The ends of the bar 39- extend under the members 3311.

The adjustment of this bracing means is also accomplished by placing a block a under the center plow bottom. The weight of the plow bottoms on each side of the center plow bottom pulls the ends of the bar 32 downwardly. The bolts 34 extending through the plate members 33 and 33a are then tightened.

By virtue of the present invention, the longitudinally arranged beams are rigidly connected so as to form a frame. A bar is associated with the rear ends of the beam, and is provided with a bracing means which reenforces the bar. The weight of the plow bottoms on the bar, which heretofore deflected the bar when the plow is in a transport position is now prevented by the bracing means, and the pull of the plow bottoms on the bar which heretofore sagged the bar when the plow is in an operating position is also prevented by the bracing means. The adjustment of the bracing means holds the plow bottoms in a level position at all times.
